Phantom Smells?

About a week ago I was in the hospital due to severe tinnitus, numbness, neck pain and high blood pressure. Now more recent things aren't much better and I seem to be having a phantom smell of acetone that my husband doesn't smell. When I went to the hospital last week I could hardly walk, hear and write. Does anyone have any of these symptoms and if so chiari/syrinx related? I am in the process of getting checked for a syrinx and am getting a bit concerned after having a black out episode in 2012 and progressive neurological symptoms that are becoming hard to ignore.

Thank you in advance for your help! :-)

My NS told me I might be affected in smelling after surgery but I did’t have a problem ,he did say I could experience it though,so there must be a connection some how.
